The medium hardware platform AXmp/AXi option was used with optional dedicated SS7 cables.

Release 4.1

In Release 4.1, SS7 signaling is sent via SIGTRAN to an Internet transfer point (ITP), therefore, dedicated SS7 cables are not attached to the Cisco BTS 10200 Softswitch. These cables have been deleted from this document.In Release 4.1, four AXmp units are used (instead of two AXmp and two AXi).06/07/2004—Added section "Set Node Addresses On the Host Machines".

This feature module is intended for use by service provider engineering and field personnel who are responsible for designing, installing, configuring, and maintaining networks that use the Cisco BTS 10200 Softswitch. The procedure in this feature module describes how to cable the medium hardware platform systems based on the Continuous Computing AXmp servers. This document is in addition to other Cisco BTS 10200 Softswitch documents that describe how to install and operate the system. Contact your Cisco account team for the documentation applicable to your specific system.

Scope and Purpose

This procedure is applicable to Cisco BTS 10200 Softswitch systems that are installed on Continuous Computing host machines, and using 2 Ethernet interfaces on each Call Agent (CA) host, and 2 Ethernet interfaces on each Element Management System (EMS) host.

Note If you are not sure about the number of interfaces to use on your system, or if you are using host machines that are not Continuous Computing-based, contact your Cisco account team for clarification.

This procedure is not applicable to Cisco BTS 10200 Softswitch systems that are already in service.

Caution Do not use this procedure to change the cabling of an in-service Cisco BTS 10200 Softswitch, because that will cause interruption of service. It is not necessary to change the cabling of in-service systems to match this document.

An example of equipment mounting for the Cisco BTS 10200 Softswitch is shown in Figure 1.

Caution Do
not use this procedure to change the cabling of an in-service Cisco BTS 10200 Softswitch, because that will cause interruption of service. It you need to change the cabling of in-service system, you must first contact your network administrator or your Cisco account team for a procedure.

Before You Start

Before you start cabling the system, perform the following verifications.

1. Verify that the hosts are already mounted in the rack according to manufacturer instructions, and labeled appropriately. Your system should have the following hardware units:

–EMS Side A

–EMS Side B

–CA Side A

–CA Side B

–Cisco 2924M Ethernet Switch A

–Cisco 2924M Ethernet Switch B

–Power distribution unit (DC systems)

–Alarm panel

2. Ask your supervisor or an authorized power installer to verify that appropriate power feeds are available, as defined in the site survey documentation for your system. The electrical power for your system must come from two separate (redundant) sources, so that a single point of failure does not cause a complete system outage.

Warning

IMPORTANT SAFETY INSTRUCTIONS

This warning symbol means danger. You are in a situation that could cause bodily injury. Before you work on any equipment, be aware of the hazards involved with electrical circuitry and be familiar with standard practices for preventing accidents. Use the statement number provided at the end of each warning to locate its translation in the translated safety warnings that accompanied this device. Statement 1071

2. The IP addresses shown in the figure are for illustration purposes only. IP address examples that begin with 10.89 indicate externally viewable addresses, and those beginning with 10.10 indicate internal nonroutable addresses. The actual IP address data for each Cisco BTS 10200 Softswitch is in the Network Information Data Sheet that was supplied with your specific system.

3. "To external NEs" refers to any of the following links in the service provider network:

•Uplinks for external access to hosts, used for management services (via SSH, SFTP, and so forth) and outbound billing data (via FTP)

•Uplinks for external communications, used for connection to external NEs and DNS services via IRDP-enabled network

4. To support full system redundancy, it is necessary to connect the two external uplinks to separate routers as shown in Figure 2. Furthermore, the routers must be connected to separate networks with diverse routing paths to the applicable external NEs and services (such as OSS, DNS, media gateways, and announcement servers).

Caution If each of the external uplinks is not connected as described in Note #3, a single point of failure could cause a traffic interruption.

5. To ensure redundancy of the DNS lookup function in the event of a network outage, it is strongly recommended to have two DNS servers reachable via separate networks with diverse routing paths.

Caution If both DNS servers become unreachable, a traffic interruption will occur.

Labeling the Cables

Make sure that you have all the cables labeled before you begin. Label the cables according to the procedure in Appendix A: Cable Labeling.

Connect Ethernet Cables To EMS and CA Units

Follow these steps to connect the Ethernet cables. Refer to Figure 1 to identify the specific units in the rack.

Step 1 Obtain the 4 Ethernet cables needed for connections between the rear panel of the Element Management Systems (EMS A and EMS B) and the two Cisco 2924M Ethernet Switches (Hub A and Hub B). These cables are listed in Table 1 in Appendix B: Cable List.

Step 3 Obtain the 4 Ethernet cables needed for connections between the rear panel of the Call Agents (CA A and CA B) and the two Cisco 2924M Ethernet Switches (Hub A and Hub B). These cables are listed in Table 1 in Appendix B: Cable List.

Connect CONSOLE Ethernet Cables to Alarm Panel

Connect the two CONSOLE Ethernet cables from the Alarm Panel to the Cisco 2924M Ethernet Switches as described in this section.

Note These two CONSOLE cables are specially designed for the CONSOLE connections. Make sure that you are using the correct cables.

Note One end of the CONSOLE cable is labeled "switch" and the other is labeled "net CCN". The "switch" end must connect to the Cisco 2924M Ethernet Switch (Hub) and the "net CCN" end must connect to the Alarm Panel.

Step 1 Refer to Figure 1 to identify which Cisco 2924M Ethernet Switch (Hub) is designated Ethernet Switch A and which is Ethernet Switch B.

Step 2 Connect the "net CCN" end of a CONSOLE cable to port SER 1 on the Alarm Panel, and the "switch" end to the CONSOLE port on the rear panel of Ethernet switch (Hub) A.

Step 3 Connect the "net CCN" end of a CONSOLE cable to port SER 2 on the Alarm Panel, and the "switch" end to the CONSOLE port on the rear panel of Ethernet switch (Hub) B.

The rear view of the alarm panel is shown in Figure 4. (The drawing is not to scale.)

Figure 4 Rear View of Alarm Panel

Connect CCPUnet Cables and Terminating Resistors

Follow these steps to connect the intershelf signaling (CCPUnet) cables and terminating resistors:

Step 1 Obtain the eight CCPUnet cables (four for CCPU A and four for CCPU B).

Step 2 Connect the CCPUnet cables between the machines as listed in Table 1. Make sure that you connect cables labeled CCPU A to the CCPU A ports, and cables labeled CCPU B to the CCPU B ports.

Note Refer to Figure 3 and Figure 4 to locate the CCPU ports on the rear panels.

Set Node Addresses On the Host Machines

The following procedure explains how to set or change the node addresses on the host machines. This procedure can be used on systems that are new, and on systems that are in service.

When multiple host machines are on a common CCPU Net, you must give each machine a unique node address.

Note If two or more machines on a common CCPU Net have identical node addresses, unpredictable operation can occur.

Step 1 Action: Disconnect CCPU Net A and CCPU Net B cables from the rear of one of the host machines.

Result: The red alarm light on the front of the unit will become illuminated. This is expected.

Why: The host machines communicate with each other through the CCPU Net cables. Disconnecting these cables will isolate each unit and prevent non-unique addressed units from interacting.

Step 2 Action: Attach to console port. Connect to CCN CLI. You should see the following prompt

nodename(XX) ccncli>

where XX is the current node address in hexadecimal and nodename is the current name of that node.

Note If you don't see this prompt, depress the following keys `control+]' followed by `.' then press the enter key two times. This will take you to the CCN CLI. If not, check your serial connection. You should be using a straight cable, connecting at 38,400bps, 8,N,1.

Why: This tells the CCN (control Computer) what state the system should be in when it is powered-up or reset.

Step 4 Action: Set the jumpers on the unit.

Background: The host machines have jumpers on the receptacle that are used to set the node address of the server. This node address is used to control the node alarming and out-of-band control commands that go from node to node.

Caution The host machines should never be configured with duplicate addresses. If duplicate addresses are used, commands designated for one system may be received by more than one system, and spurious operation may result. For example, if two nodes have duplicate addresses, turning one node off may cause the second node to turn off.

Jumper Settings: The jumpers are on the rear of the receptacle that remains attached to the cabinet even when the core is removed. These jumpers are shown in Figure 5.

Figure 5 View of Jumpers and Bit Locations

Using shunt jumpers, systems may be configured to different addresses. Figure 6 shows several sample configurations.

Step 3 If your local network documentation calls for 100 Mb Ethernet, connect the applicable network uplink cables as listed in Table 1. Ports #21 through 24 are available for this use.

Step 4 After installing the uplink cables, record the necessary information on a copy of Table 1 or similar document according to local procedures.

Connect Intershelf Power and Grounding Cables

After obtaining approval from a supervisor, an authorized power installer should follow these steps to connect the intershelf power and grounding cables to the individual machines in the Cisco BTS 10200 Softswitch. The intershelf power cables are provided with your shipment.

Caution Ensure redundancy of power feeds to your system, so that a single point of failure does not cause a loss of traffic:

— For DC systems, power each host from two separate (redundant) DC power feeds.
— For AC systems, power Side A hosts from a separate power source than Side B.

SAVE THESE INSTRUCTIONS

Step 1 For DC-powered systems, connect the cables as follows:

a. Use the specific DC power cable that was provided for each machine in your shipment.

b. Connect the intershelf DC power cables from the power distribution unit (PDU) to each of the devices in the rack. There are two intershelf DC power cables per machine (one for power feed A and one for B). See Table 1 for the complete cabling list.

c. Following local electrical codes, connect the ground cables from each of the devices in the rack to the PDU grounding point (either of the two grounding screws on the PDU rear panel). See Table 1 for the complete cabling list.

Step 2 For AC-powered systems, connect the cables as follows:

a. Use the specific AC power cable that was provided for each machine in your shipment.

b. For each A Side machine (A Side EMS, CA, and Ethernet Switch) connect the intershelf AC power cable from the device to one of the AC power strips.

c. For each A Side machine (A Side EMS, CA, and Ethernet Switch) connect the intershelf AC power cable from the device to the other AC power strip.

d. Connect the intershelf AC power cable from the Alarm Panel to either of the power strips.

Warning

This equipment must be grounded. Never defeat the ground conductor or operate the equipment in the absence of a suitably installed ground conductor. Contact the appropriate electrical inspection authority or an electrician if you are uncertain that suitable grounding is available. Statement 1024

Connect Site Power and Grounding Cables

This section describes how to connect site power and grounding cables for DC- and AC-powered systems.

Note Cisco strongly recommends that you use uninterruptible power for both AC and DC systems. The uninterruptible supply should be engineered to support system operation through any possible power interruption.

Caution Ensure redundancy of power feeds to your system, so that a single point of failure does not cause a loss of traffic:

For DC systems, power the A and B power feeds on the PDU from two separate (redundant) DC sources.
For AC systems, power each of the power strips from separate (redundant) AC power feeds.

DC-Powered Systems

Note For DC systems the nominal current rating for a complete Cisco BTS 10200 Softswitch system is 26A at -48 VDC, and the maximum current rating is 40A at -48 VDC.

After obtaining approval from a supervisor, an authorized power installer should follow these steps to connect the DC power from the office batteries to the PDU.

SAVE THESE INSTRUCTIONS

Step 1 Following local electrical codes, connect power cables from the power distribution unit (PDU) to dual feeds ("A" and "B") on the office batteries. Use Listed two-hole crimped lugs on the PDU side of the cable.

Step 2 Following local electrical codes, connect the PDU grounding point (both of the two grounding screws on the PDU rear panel) to CO earth ground using 6 AWG wire or heavier and a Listed two-hole crimped lug.

Warning

This equipment must be grounded. Never defeat the ground conductor or operate the equipment in the absence of a suitably installed ground conductor. Contact the appropriate electrical inspection authority or an electrician if you are uncertain that suitable grounding is available. Statement 1024

AC-Powered Systems

Follow these steps to connect site AC power.

Note For installations in the U.S.A. and Canada, two separate (redundant) circuits of 20A 120 VAC are required. The circuits must be sourced from separate transformer phases on separate breakers such that a single breaker trip will not disable both. They should also have dedicated ("green wire") earth grounds back to the same distribution panel grounding point. For countries other than the U.S.A. or Canada, contact your Cisco account team for electrical requirements.

Step 1 An authorized electrician must verify that the power source is adequate for the system.

Step 2 Connect each of the power strips to a separate AC feed as designated by the electrician.

Enable IRDP

This section explains how to enable IRDP functionality on the Cisco BTS 10200 Softswitch and on the network router.

Enable IRDP on the Cisco BTS 10200 Softswitch

Follow these steps to enable IRDP on the Cisco BTS 10200 Softswitch.

Note You should already have the Cisco BTS 10200 Softswitch application software installed on the system.

Step 1 Log in to EMS Side A as root user.

Step 2 Remove the defaultrouter file from /etc.

Step 3 There should be three default routes in the routing table. Remove all three of these with the following command:

Enable IRDP on Adjacent Cisco Routers

If you are enabling IRDP on Cisco routers adjacent to the Cisco BTS 10200 Softswitch, follow these steps. If you have any questions about setup of these routers, contact your system administrator. If you need additional assistance, contact Cisco TAC.

Step 1 Verify that you have the Network Information Data Sheet (NIDS) applicable to this Cisco BTS 10200 Softswitch. If necessary, contact your network administrator to verify that you have the correct NIDS.

Step 2 On default gateway interfaces for Network 1 and Network 2 (as defined in the NIDS) enable IRDP using the following commands:

config t

interface <Fast Ethernet interface number (see NIDS)>

ip irdp

ip irdp maxadvertinterval 4

ip irdp minadvertinterval 3

ip irdp holdtime 10

Step 3 Validate the configuration by performing the following command on both CA/FS hosts and both EMS hosts:

login as root

#netstat -rn

Step 4 View the display and verify that each default route was populated dynamically by IRDP.

Verify IRDP Functions

Follow these steps to verify that IRDP is functioning properly on the network:

CA Side A

Step 2 Display the IRDP daemon status by entering the following command:

ps -ef|grep in.rdisc

Step 3 View the display and verify that each default route was populated dynamically by IRDP. The display should include the following information: /usr/sbin/in.rdisc -s -f. (This indicates that IRDP is running properly.)

Step 4 Display the routing table by entering the following command:

netstat -rn

Step 5 Verify that the routing table shows two default routes, one on interface NET 0 and one on NET 1.

Step 6 Unplug the interface NET 0 link at the back of CA Side A.

Step 7 Display the routing table by entering the following command:

netstat -rn

Step 8 Verify that the route for interface NET 0 does not appear in the routing table.

Note When a link is unplugged or plugged back in, it may take 5 to 10 seconds for the IRDP function to automatically update.

Step 9 Plug the interface NET 0 link back in to CA Side A.

Step 10 Display the routing table (netstat -rn) and verify that the route for interface NET 0 appears in the routing table again.

CA Side B

Verify Interfaces

Follow these steps to verify that all interfaces are configured on all computing elements:

Step 1 If the Cisco BTS 10200 Softswitch application software has already been installed on the system, go to Step 2. If the application has not been installed, go to Step 4.

Step 2 (If the Cisco BTS 10200 Softswitch application software has already been installed on the system) check the interface configurations using the following command on each of the four platforms (two EMS units and two CA/FS units):

Enter: checkCFG

Step 3 The system should display the message Validating..... If no errors are found during validation, the system will display the message No errors found. Verify that the No errors found message is displayed.

Note If the system does display an error, contact Cisco TAC for assistance.

Step 4 If the Cisco BTS 10200 Softswitch application software has not been installed on the system, install the application using the Application Installation procedure provided by Cisco. That procedure contains the appropriate commands to check the configurations (checkCFG).

Appendix A: Cable Labeling

Cables are labeled at both ends with the cable numbers listed in Table 1. Follow these steps to create and attach the labels.

Note As listed in Table 1, some of the cables require labeling and others do not.

Step 1 Make each label by copying the applicable number from Table 1 onto the label. Be sure to duplicate the number several times onto the label, as shown in Figure 7, to make it easier to read. (If desired, make the labels for all cables in one print run.)

Step 2 On a work bench or assembly table, position a cable so that one connector is on your left and the cable goes off to the right. (See Figure 7.)

Step 3 Attach the appropriate label to the cable as shown in Figure 7.

Step 4 Turn the cable around so that the other connector is on your left with the cable going off to the right.
